We need nuclear power to solve climate change

  • 0:01 - 0:03
    It's easy to forget that last night,
  • 0:04 - 0:08
    one billion people went to sleep
    without access to electricity.
  • 0:08 - 0:09
    One billion people.
  • 0:10 - 0:15
    Two and a half billion people
    did not have access to clean cooking fuels
  • 0:16 - 0:17
    or clean heating fuels.
  • 0:18 - 0:21
    Those are the problems
    in the developing world.
  • 0:21 - 0:24
    And it's easy for us not to be empathetic
  • 0:24 - 0:26
    with those people
    who seem so distanced from us.
  • 0:26 - 0:29
    But even in our own world,
    the developed world,
  • 0:30 - 0:33
    we see the tension of stagnant economies
  • 0:33 - 0:36
    impacting the lives of people around us.
  • 0:36 - 0:39
    We see it in whole pieces of the economy,
  • 0:40 - 0:43
    where the people involved
    have lost hope about the future
  • 0:43 - 0:45
    and despair about the present.
  • 0:45 - 0:47
    We see that in the Brexit vote.
  • 0:48 - 0:51
    We see that in the Sanders/Trump
    campaigns in my own country.
  • 0:52 - 0:56
    But even in countries as recently
    turning the corner
  • 0:57 - 0:58
    towards being in the developed world,
  • 0:58 - 1:00
    in China,
  • 1:00 - 1:02
    we see the difficulty
    that President Xi has
  • 1:03 - 1:08
    as he begins to un-employ so many people
    in his coal and mining industries
  • 1:08 - 1:10
    who see no future for themselves.
  • 1:11 - 1:14
    As we as a society
    figure out how to manage
  • 1:14 - 1:16
    the problems of the developed world
  • 1:16 - 1:18
    and the problems of the developing world,
  • 1:18 - 1:21
    we have to look at how we move forward
  • 1:21 - 1:25
    and manage the environmental impact
    of those decisions.
  • 1:26 - 1:29
    We've been working on this problem
    for 25 years, since Rio,
  • 1:29 - 1:31
    the Kyoto Protocols.
  • 1:31 - 1:34
    Our most recent move is the Paris treaty,
  • 1:35 - 1:37
    and the resulting climate agreements
  • 1:37 - 1:40
    that are being ratified
    by nations around the world.
  • 1:40 - 1:42
    I think we can be very hopeful
  • 1:42 - 1:45
    that those agreements,
    which are bottom-up agreements,
  • 1:45 - 1:48
    where nations have said
    what they think they can do,
  • 1:48 - 1:52
    are genuine and forthcoming
    for the vast majority of the parties.
  • 1:53 - 1:55
    The unfortunate thing
  • 1:55 - 1:59
    is that now, as we look
    at the independent analyses
  • 1:59 - 2:02
    of what those climate treaties
    are liable to yield,
  • 2:03 - 2:06
    the magnitude of the problem
    before us becomes clear.
  • 2:07 - 2:11
    This is the United States
    Energy Information Agency's assessment
  • 2:12 - 2:16
    of what will happen if the countries
    implement the climate commitments
  • 2:16 - 2:18
    that they've made in Paris
  • 2:18 - 2:20
    between now and 2040.
  • 2:21 - 2:25
    It shows basically CO2 emissions
    around the world
  • 2:25 - 2:27
    over the next 30 years.
  • 2:28 - 2:32
    There are three things that you need
    to look at and appreciate.
  • 2:32 - 2:36
    One, CO2 emissions are expected
    to continue to grow
  • 2:36 - 2:38
    for the next 30 years.
  • 2:39 - 2:42
    In order to control climate,
  • 2:42 - 2:45
    CO2 emissions have to literally go to zero
  • 2:46 - 2:50
    because it's the cumulative emissions
    that drive heating on the planet.
  • 2:50 - 2:55
    This should tell you that we are losing
    the race to fossil fuels.
  • 2:56 - 2:57
    The second thing you should notice
  • 2:57 - 3:02
    is that the bulk of the growth
    comes from the developing countries,
  • 3:02 - 3:05
    from China, from India,
    from the rest of the world,
  • 3:05 - 3:08
    which includes South Africa
    and Indonesia and Brazil,
  • 3:09 - 3:12
    as most of these countries
    move their people
  • 3:12 - 3:15
    into the lower range of lifestyles
  • 3:15 - 3:19
    that we literally take for granted
    in the developed world.
  • 3:20 - 3:23
    The final thing that you should notice
  • 3:23 - 3:25
    is that each year,
  • 3:25 - 3:32
    about 10 gigatons of carbon are getting
    added to the planet's atmosphere,
  • 3:33 - 3:36
    and then diffusing into the ocean
    and into the land.
  • 3:36 - 3:41
    That's on top of the 550 gigatons
    that are in place today.
  • 3:42 - 3:44
    At the end of 30 years,
  • 3:44 - 3:48
    we will have put 850 gigatons
    of carbon into the air,
  • 3:49 - 3:51
    and that probably goes a long way
  • 3:51 - 3:58
    towards locking in a 2-4 degree C increase
    in global mean surface temperatures,
  • 3:58 - 4:01
    locking in ocean acidification
  • 4:01 - 4:03
    and locking in sea level rise.
  • 4:04 - 4:07
    Now, this is a projection made by men
  • 4:08 - 4:10
    by the actions of society,
  • 4:11 - 4:13
    and it's ours to change, not to accept.
  • 4:14 - 4:18
    But the magnitude of the problem
    is something we need to appreciate.
  • 4:19 - 4:21
    Different nations make
    different energy choices.
  • 4:21 - 4:23
    It's a function
    of their natural resources.
  • 4:23 - 4:25
    It's a function of their climate.
  • 4:25 - 4:30
    It's a function of the development path
    that they've followed as a society.
  • 4:31 - 4:34
    It's a function of where
    on the surface of the planet they are.
  • 4:34 - 4:37
    Are they where it's dark
    a lot of the time,
  • 4:37 - 4:39
    or are they at the mid-latitudes?
  • 4:39 - 4:43
    Many, many, many things
    go into the choices of countries,
  • 4:43 - 4:45
    and they each make a different choice.
  • 4:47 - 4:50
    The overwhelming thing
    that we need to appreciate
  • 4:50 - 4:52
    is the choice that China has made.
  • 4:53 - 4:55
    China has made the choice,
  • 4:55 - 4:58
    and will make the choice, to run on coal.
  • 4:58 - 5:00
    The United States has an alternative.
  • 5:00 - 5:02
    It can run on natural gas
  • 5:02 - 5:06
    as a result of the inventions
    of fracking and shale gas,
  • 5:06 - 5:08
    which we have here.
  • 5:08 - 5:09
    They provide an alternative.
  • 5:11 - 5:13
    The OECD Europe has a choice.
  • 5:14 - 5:17
    It has renewables that it can afford
    to deploy in Germany
  • 5:17 - 5:20
    because it's rich enough
    to afford to do it.
  • 5:20 - 5:25
    The French and the British
    show interest in nuclear power.
  • 5:26 - 5:30
    Eastern Europe, still very heavily
    committed to natural gas and to coal,
  • 5:30 - 5:33
    and with natural gas
    that comes from Russia,
  • 5:33 - 5:35
    with all of its entanglements.
  • 5:36 - 5:38
    China has many fewer choices
  • 5:38 - 5:40
    and a much harder row to hoe.
  • 5:42 - 5:45
    If you look at China, and you ask yourself
  • 5:45 - 5:47
    why has coal been important to it,
  • 5:47 - 5:49
    you have to remember what China's done.
  • 5:50 - 5:53
    China brought people to power,
    not power to people.
  • 5:53 - 5:56
    It didn't do rural electrification.
  • 5:56 - 5:58
    It urbanized.
  • 5:58 - 6:02
    It urbanized by taking low-cost labor
    and low-cost energy,
  • 6:02 - 6:04
    creating export industries
  • 6:04 - 6:07
    that could fund a tremendous
    amount of growth.
  • 6:08 - 6:10
    If we look at China's path,
  • 6:10 - 6:14
    all of us know that prosperity in China
    has dramatically increased.
  • 6:15 - 6:19
    In 1980, 80 percent of China's population
  • 6:19 - 6:22
    lived below the extreme poverty level,
  • 6:22 - 6:26
    below the level of having
    $1.90 per person per day.
  • 6:27 - 6:32
    By the year 2000, only 20 percent
    of China's population
  • 6:32 - 6:35
    lived below the extreme poverty level --
  • 6:35 - 6:37
    a remarkable feat,
  • 6:38 - 6:40
    admittedly, with some costs
    in civil liberties
  • 6:40 - 6:43
    that would be tough to accept
    in the Western world.
  • 6:45 - 6:47
    But the impact of all that wealth
  • 6:47 - 6:51
    allowed people to get
    massively better nutrition.
  • 6:51 - 6:54
    It allowed water pipes to be placed.
  • 6:54 - 6:57
    It allowed sewage pipes to be placed,
  • 6:57 - 7:00
    dramatic decrease in diarrheal diseases,
  • 7:01 - 7:03
    at the cost of some outdoor air pollution.
  • 7:04 - 7:06
    But in 1980, and even today,
  • 7:06 - 7:10
    the number one killer in China
    is indoor air pollution,
  • 7:11 - 7:16
    because people do not have access
    to clean cooking and heating fuels.
  • 7:16 - 7:18
    In fact, in 2040,
  • 7:20 - 7:25
    it's still estimated
    that 200 million people in China
  • 7:25 - 7:28
    will not have access
    to clean cooking fuels.
  • 7:29 - 7:31
    They have a remarkable path to follow.
  • 7:33 - 7:38
    India also needs to meet the needs
    of its own people,
  • 7:38 - 7:40
    and it's going to do that by burning coal.
  • 7:40 - 7:46
    When we look at the EIA's projections
    of coal burning in India,
  • 7:47 - 7:51
    India will supply nearly four times
    as much of its energy from coal
  • 7:52 - 7:54
    as it will from renewables.
  • 7:55 - 7:58
    It's not because they don't know
    the alternatives;
  • 7:58 - 8:02
    it's because rich countries
    can do what they choose,
  • 8:02 - 8:04
    poor countries do what they must.
  • 8:06 - 8:10
    So what can we do to stop
    coal's emissions in time?
  • 8:11 - 8:16
    What can we do that changes
    this forecast that's in front of us?
  • 8:16 - 8:20
    Because it's a forecast that we can change
    if we have the will to do it.
  • 8:21 - 8:25
    First of all, we have to think
    about the magnitude of the problem.
  • 8:25 - 8:27
    Between now and 2040,
  • 8:27 - 8:33
    800 to 1,600 new coal plants
    are going to be built around the world.
  • 8:34 - 8:39
    This week, between one and three
    one-gigawatt coal plants
  • 8:39 - 8:41
    are being turned on around the world.
  • 8:42 - 8:46
    That's happening regardless
    of what we want,
  • 8:46 - 8:48
    because the people
    that rule their countries,
  • 8:48 - 8:51
    assessing the interests of their citizens,
  • 8:51 - 8:54
    have decided it's in the interest
    of their citizens to do that.
  • 8:55 - 8:59
    And that's going to happen
    unless they have a better alternative.
  • 9:00 - 9:03
    And every 100 of those plants will use up
  • 9:04 - 9:07
    between one percent and three percent
  • 9:07 - 9:08
    of the Earth's climate budget.
  • 9:09 - 9:13
    So every day that you go home
    thinking that you should do something
  • 9:13 - 9:14
    about global warming,
  • 9:15 - 9:17
    at the end of that week, remember:
  • 9:17 - 9:21
    somebody fired up a coal plant
    that's going to run for 50 years
  • 9:21 - 9:24
    and take away your ability to change it.
  • 9:26 - 9:30
    What we've forgotten is something
    that Vinod Khosla used to talk about,
  • 9:30 - 9:33
    a man of Indian ethnicity
    but an American venture capitalist.
  • 9:33 - 9:36
    And he said, back in the early 2000s,
  • 9:36 - 9:40
    that if you needed to get
    China and India off of fossil fuels,
  • 9:40 - 9:44
    you had to create a technology
    that passed the "Chindia test,"
  • 9:45 - 9:47
    "Chindia" being the appending
    of the two words.
  • 9:48 - 9:50
    It had to be first of all viable,
  • 9:50 - 9:54
    meaning that technically, they could
    implement it in their country,
  • 9:54 - 9:57
    and that it would be accepted
    by the people in the country.
  • 9:58 - 10:05
    Two, it had to be a technology
    that was scalable,
  • 10:05 - 10:08
    that it could deliver the same benefits
  • 10:08 - 10:11
    on the same timetable as fossil fuels,
  • 10:11 - 10:15
    so that they can enjoy the kind of life,
    again, that we take for granted.
  • 10:16 - 10:18
    And third, it had to be cost-effective
  • 10:18 - 10:21
    without subsidy or without mandate.
  • 10:21 - 10:24
    It had to stand on its own two feet;
  • 10:24 - 10:28
    it could not be maintained
    for that many people
  • 10:28 - 10:31
    if in fact, those countries
    had to go begging
  • 10:31 - 10:35
    or had some foreign country say,
    "I won't trade with you,"
  • 10:35 - 10:39
    in order to get
    the technology shift to occur.
  • 10:40 - 10:42
    If you look at the Chindia test,
  • 10:42 - 10:47
    we simply have not come up
    with alternatives that meet that test.
  • 10:47 - 10:50
    That's what the EIA forecast tells us.
  • 10:51 - 10:54
    China's building 800 gigawatts of coal,
  • 10:55 - 10:57
    400 gigawatts of hydro,
  • 10:58 - 11:00
    about 200 gigawatts of nuclear,
  • 11:01 - 11:05
    and on an energy-equivalent basis,
    adjusting for intermittency,
  • 11:05 - 11:07
    about 100 gigawatts of renewables.
  • 11:08 - 11:09
    800 gigawatts of coal.
  • 11:10 - 11:13
    They're doing that, knowing the costs
    better than any other country,
  • 11:13 - 11:16
    knowing the need better
    than any other country.
  • 11:16 - 11:19
    But that's what they're aiming for in 2040
  • 11:19 - 11:21
    unless we give them a better choice.
  • 11:22 - 11:24
    To give them a better choice,
  • 11:24 - 11:26
    it's going to have to meet
    the Chindia test.
  • 11:26 - 11:29
    If you look at all the alternatives
    that are out there,
  • 11:29 - 11:31
    there are really two
    that come near to meeting it.
  • 11:32 - 11:36
    First is this area of new nuclear
    that I'll talk about in just a second.
  • 11:36 - 11:39
    It's a new generation of nuclear plants
    that are on the drawing boards
  • 11:39 - 11:41
    around the world,
  • 11:41 - 11:43
    and the people who are
    developing these say
  • 11:43 - 11:47
    we can get them
    in position to demo by 2025
  • 11:47 - 11:51
    and to scale by 2030,
    if you will just let us.
  • 11:51 - 11:54
    The second alternative
    that could be there in time
  • 11:55 - 11:58
    is utility-scale solar
    backed up with natural gas,
  • 11:58 - 12:00
    which we can use today,
  • 12:00 - 12:03
    versus the batteries
    which are still under development.
  • 12:05 - 12:07
    So what's holding new nuclear back?
  • 12:08 - 12:11
    Outdated regulations
    and yesterday's mindsets.
  • 12:12 - 12:16
    We have not used our latest
    scientific thinking on radiological health
  • 12:16 - 12:19
    to think how we communicate
    with the public
  • 12:19 - 12:21
    and govern the testing
    of new nuclear reactors.
  • 12:22 - 12:26
    We have new scientific knowledge
    that we need to use
  • 12:26 - 12:30
    in order to improve the way
    we regulate nuclear industry.
  • 12:31 - 12:33
    The second thing is we've got a mindset
  • 12:33 - 12:36
    that it takes 25 years
    and 2 to 5 billion dollars
  • 12:36 - 12:38
    to develop a nuclear power plant.
  • 12:38 - 12:42
    That comes from the historical,
    military mindset
  • 12:42 - 12:45
    of the places nuclear power came from.
  • 12:45 - 12:48
    These new nuclear ventures are saying
  • 12:48 - 12:50
    that they can deliver power
    for 5 cents a kilowatt hour;
  • 12:51 - 12:54
    they can deliver it
    for 100 gigawatts a year;
  • 12:55 - 12:57
    they can demo it by 2025;
  • 12:57 - 13:00
    and they can deliver it in scale by 2030,
  • 13:01 - 13:03
    if only we give them a chance.
  • 13:04 - 13:07
    Right now, we're basically
    waiting for a miracle.
  • 13:08 - 13:09
    What we need is a choice.
  • 13:10 - 13:13
    If they can't make it safe,
    if they can't make it cheap,
  • 13:13 - 13:15
    it should not be deployed.
  • 13:15 - 13:19
    But what I want you to do
    is not carry an idea forward,
  • 13:19 - 13:20
    but write your leaders,
  • 13:20 - 13:23
    write the head of the NGOs you support,
  • 13:23 - 13:26
    and tell them to give you the choice,
  • 13:26 - 13:27
    not the past.
  • 13:27 - 13:29
    Thank you very much.
  • 13:29 - 13:33

Title:
We need nuclear power to solve climate change
Speaker:
Joe Lassiter
Description:

Joe Lassiter is a deep thinker and straight talker focused on developing clean, secure and carbon-neutral supplies of reliable, low-cost energy. His analysis of the world's energy realities puts a powerful lens on the stubbornly touchy issue of nuclear power, including new designs for plants that can compete economically with fossil fuels. We have the potential to make nuclear safer and cheaper than it's been in the past, Lassiter says. Now we have to make the choice to pursue it.
